How Does AI Transcription Work? Key Features & Real-World Use Cases

Artificial Intelligence was built to assist humanity with tasks that were too mundane to focus on; thus, a variety of tools were developed to establish AI assistance in every field - writing, mathematics, and even therapy.

The world is rapidly moving forward with new advancements in technology, and learning how AI transcription works is becoming increasingly valuable across multiple industries.

Transcription, as a profession, is no different. Mere conversion of verbal speech into written text requires highly trained individuals today, but AI is slowly shifting into their now-abandoned cubicles as a more adaptable and cost-efficient option.

What is AI Transcription?

AI Transcription is an automatic speech recognition (ASR) technology that converts spoken words into written text. Understanding how AI transcription works begins with recognizing the role of ASR technology in converting spoken words into written text. It uses technological innovations such as natural speech processing, machine learning, and artificial narrow intelligence, among others. 

It eliminates the need to make notes manually, creates both time and room for other applications of the mind, and helps massively in retention and understanding of whatever needs transcription, like court cases, classes, perpetrator interviews by detectives, and so on. 

There are two types of AI Transcriptors:

When exploring how AI transcription works, it's important to distinguish between its two main types: real-time and batch processing.

1. Real-time AI Transcription

This type introduces the ability to transcribe events as they are happening, introduces ultra-low latency, and allows for perhaps the fastest release of official documents, eliminating an entire delegation circle and the requirement of time, as it can happen with a button press.

Accuracy, however, sits at 65%~ making it miles away in terms of human accuracy, but still a solid option to transcribe, albeit requiring a little editing later on.

2. Batch AI Transcription

A pre-recorded audio can be uploaded and subsequently transcribed by the batch AI transcription tool, introducing hours of latency but a much higher accuracy and a time relaxation, compared to its more technically advanced counterpart. 

AI transcription is a relatively new service, yet vendors looking to capitalise on a new market are already in the industry, rapidly developing fame for themselves in their respective interest areas. 

Some of these services include, but are not limited to, AWS (Amazon Web Services), Sonix, Otter.ai, VoiceNotes, and VoiceToNotes.

How does AI Transcription work?

To understand how AI transcription works, let's first compare it with how we humans naturally process language. See, we have this amazing ability to instantly get accents, tones, and even hidden meanings depending on the situation.

Take the word ‘bat’ for example — if someone says:

• “I saw a bat sleeping in a tree,” You know it's the animal.
• But if they say, “I hit the ball with my bat.” You know it’s about cricket (or baseball).

Simple for us, but AI? Not so much.

AI needs some serious training to even come close to this kind of understanding. That’s where machine learning steps in. We feed AI tons of data — conversations, speeches, different accents, tones, even weird slang — and over time, it starts to recognize patterns.

But learning words isn’t enough. That’s where Natural Language Processing (NLP) comes in. NLP teaches AI how sentences work, what words mean together, and how context changes everything. Basically, it gives AI that "aha!" moment humans have all the time.

Now, to make AI even smarter, we throw in deep learning — complex neural networks that mimic how our brains process information. This helps AI deal with complicated language structures that even some humans struggle with.

Finally, all of this magic comes together in Automated Speech Recognition (ASR) — the core tech behind AI transcription. ASR listens to speech, slices it into tiny pieces, recognizes words, figures out what was meant, and converts it into text.

And that’s how AI transcription works. Of course, it’s not perfect — background noise, multiple people talking, thick accents — all these still confuse AI sometimes. But every day, it’s getting better and better.

Tutorial for using AI Transcription

This can branch into the two options mentioned above - batch or real-time. Steps for both of them, at large, remain the same, the only difference being the step involving uploading audio files, which will be replaced by a microphone button you can press and begin transcribing.

The steps are:

Step 1

Choose an AI transcription service. Make sure you read through its terms and conditions and go through its reviews before using it. 

For example, you choose voicetonotes.ai for real-time transcription or making text notes from your voice. First, visit the website and you need to sign up. 

Step 2           

After signing in, you will see a good-looking dashboard. First, press the record button, begin speaking, and start making notes.

(PS: make sure you are in a silent room with only one speaker for best results. Also use the AI tool that recognises the language being spoken, as many only understand and transcribe English.)

Step 3 

After transcribing real-time voice, you can enhance your text notes, fix grammar mistakes, or rephrase sentences for better and clearer understanding.

Step 4

You can now download or export your transcript in any of the popular text formats, or simply copy and use it whenever you want. Transcription is complete - that easily.

Key Features of Artificial Intelligence Transcription 

The following features illustrate how AI transcription works to deliver fast and reliable transcriptions.

1. Automatic conversion: AI transcription converts spoken words into written text instantly and automatically, no need for brain gymnastics here!
2. High Accuracy: Modern AI transcription tools offer much higher accuracy and lower error rates compared to those state just a few years ago
3. Multilingual support: AI transcription (in certain cases) can also recognise many languages, making transcription and recording of these languages that much easier. These AI tools also offer translation as a nifty bonus.
4. Multi-speaker support: Some AI tools offer multi-speaker tools, which colour code and recognise multiple speakers to make report writing and future releases that much easier
5. Contextual understanding: AI tools now have impressively complex deep learning mechanics that allow them to understand semantics and context very easily.
6. Scalability: AI tools can handle hours worth of audio recordings and several-hour-long meetings, and not lose any efficiency in the process
7. Efficiency: In the process of converting these multiple hour-long audios and such, AI does not get slowed down by fatigue or tiredness. It can do its work as fast as you can throw some its way.
8. Rephrase Tool: AI tools like VoiceToNote can also rephrase what you spoke after it has transcribed it to improve tonality, among other factors that might be putting your speech down
9. Grammar correction: Transcription can be messy, and people’s spoken English much more so. AI tools can correct grammar post-transcription to make the transcript presentable. 

Top Use Cases for AI Transcription

AI transcription will directly replace human transcriptionists in professions around the world. 

The most important use cases of this revolutionary technology are in the Judicial, Medical, Journalistic, and Law Enforcement sectors.

1. Judicial Sector: Court Cases are documented and use transcriptionists, usually with a typewriter, noting down everything the lawyers, witnesses, judges, jury, suspect, etc, say in the case. 
2. It is a very hectic work process, but can be mostly mitigated through high-tech AI tools to do the transcription instead. The transcriptionist can supervise the AI’s work and correct any mistakes it might make. 
3. Medical Sector: Doctors and patients both want recordings of each other for training and, well, getting better purposes. AI transcription can make it much easier by providing notes on the spot. 

Also, doctors’ orders in hospital wards can also be immediately registered on medical software, leaving very little for the nurses to err on. 

As a nice bonus, AI transcription also offers end-to-end encryption, at least apps like VoiceToNotes do, which protects the patient’s privacy from being exploited and entering the pockets of big tech.

1. Journalistic Sector: Interviews, live field recordings, sting operations, the use case for AI transcription for journalists is truly endless. Having a tool that converts overglorified air vibrations to concrete text helps in putting out truly high-quality news stories and might end up becoming a way to keep politicians and prolific public figures accountable.
2. Law Enforcement: Interviews taken by detectives or police officers, registration of crime scenes, and brainstorming can all be done through AI transcription, making flip-open notepads redundant, regardless of how cool they look
3. (Bonus!) Therapy: Psychologists and therapists take notes of their patients and what they tell them. Having a truly secure end-to-end encrypted AI transcription tool can help the therapist to truly focus on their patient, while the tool makes the notes for them.

(Bonus!) Education: Students can use AI transcription tools to record lectures and make notes while they concentrate on class (or sleep), and lecturers can use them to record, transcribe, and field doubts to better their lesson plan and improve their teaching methods.

Benefits of AI Transcription

There are many benefits of AI transcription, which far outweigh the shortcomings. 

If anything, the shortcomings preserve the jobs of transcriptionists, and the benefits would make their and their employer’s lives so much easier. The benefits are:

1. Real-time, highly accurate transcription: Real-time transcription is much more difficult to pull off, as it is also a newer technology. 
2. AI-powered content enhancement: Tools such as Sonix, VoicetoNotes use their complex and advanced deep learning engines to enhance and make all of the content spoken by you or by anyone else sharper and more comprehensible.
3. End-to-end encryption: For therapy, medical, and even educational sectors, user privacy is extremely important, which AI transcription ensures using high-end technology. 

VoicetoNotes is the only one in its freemium segment that offers it, while AWS, etc, which are more expensive, established brands or parts of one, offer a more robust encryption feature set but are not accessible.

Seamless integration: Many AI tools integrate seamlessly into different kinds of applications, like WhatsApp, X, and  Instagram, to further the user experience.

AI vs Manual Transcriptions:

To highlight the difference between AI and Manual transcriptions, and understand the users for both kinds, a direct 1:1 contrast proves itself necessary. As such, here is a table doing that:

Data Insights and Market Stats

At the top of the level, lab-tested and expensive AI models are 95% accurate. These statistics offer a deeper look into how AI transcription works under both ideal and real-world conditions.

Real-world conditions weave a different tale. Accuracy drops to about 60%~, with varying factors such as accents, multiple speakers, and background noise. Given the infancy of the technology, the number still manages to impress.

Human transcriptionists achieve about 99% accuracy, something AI is still years away from. However, the convenience and ease of usage provide an easy solution for all those looking to kick back a little and take their hands off the wheel.

Real-time transcriptions also drop accuracy by 7%~ compared to batch transcriptions

Latency Results:

Similar top-of-the-line AI models are a few hundred milliseconds away from 1:1 perfection, but the same stands true for real-world scenarios

The accuracy hit is still very much present, however.

Error Rate Results:  Real-time AI transcriptions still have problems with punctuation and grammar, making fragmented sentences and disassociated thoughts

Background noise is enough to disarm an AI model’s real-time accuracy, making real-world applications too slim to recommend

Multiple speaker recognition is still in its conception stage, and while improving, it will take years to reach human levels.
